Mesothelioma Cancer

By Husseiny Ahmed

What is mesothelioma? This name refers to a very rare type of cancer that has some thousands of cases on all over the world. This type on cancer is caused by inhalation of Asbestos. Asbestos are some materials used in construction manufacturers.

There are four types of mesothelioma cancer, three types of them are very dangerous and are very hard to treat, there three types are Pleural Mesothelioma “Tumors develop in lung lining”, the second dangerous type is Peritoneal Mesothelioma “Tumors develop on Peritoneum, the outer membrane of the internal organs in the abdominal cavity, the third dangerous type is Pericardial Mesothelioma “Tumors develop in the sac that contain the heart”. The fourth type is Benign Mesothelioma and this type is not dangerous.

Pleural Mesothelioma is the most common type of that cancer, the most patients of that cancer are diagnosed as victims. The main reason for this disease is the inhalation of Asbestos, these Asbestos was used at construction manufacturers especially the cement manufacturing companies.

In fact, they can make a law suite to have their compensation rights from the manufacturing companies that let them exposure to Asbestos. the settlement in such cases can reach millions of dollars. There are people can help victims to get their rights and there are many lawyers specify in such settlements.

It is less common than pleural mesothelioma but it is more dangerous. In this case of cancer, tumors develop in the peritoneum, if you don’t know what is peritoneum exactly, Peritoneum is the outer line surrounds the internal organs in abdominal cavity.

Pericardial Mesothelioma, the least common type of that cancer, in this case the tumors develop in the heart lining or Pericardium.

The most critical form of mesothelioma is the malignant form. Known as malignant mesothelioma, the primary causal factor is asbestos infection. According to the US National Cancer Institute, “Malignant mesothelioma is a disease in which cancer (malignant) cells are found in the sac lining the chest (the pleura), the lining of the abdominal cavity (the peritoneum) or the lining around the heart (the pericardium).”

Mesothelioma can be classified into three types – pleural mesothelioma, peritoneal mesothelioma and pericardial mesothelioma. Pleural mesothelioma refers to a cancer of the lining of the lung (pleura), peritoneal mesothelioma refers to a cancer of the abdominal cavity (peritoneum) lining, and pericardial mesothelioma is a cancer that occurs in the lining that surrounds the heart (pericardium). The subtypes of mesothelioma are of three basic types, one very aggressive, one least aggressive, and one lying between the two extremes.

Malignant mesothelioma can be diagnosed through several imaging techniques. These imaging techniques enable physicians to assess mesothelioma. Once mesothelioma is suspected, patients are advised to undergo several tests, like X-ray, Computed Tomography (CT) scan, Magnetic Resonance Imaging (MRI) scans, and Positron Emission Tomography (PET) imaging. The physician may also like to undertake special mesothelioma tests like thoracoscopy, peritoneoscopy and biopsy.

Learning about the stage of mesothelioma is a critical factor that helps physicians to decide the treatment plan. If the cancer is confined to the pleura, mesothelioma is considered localized. If the cancer spreads beyond the pleura and to other parts of the body such as the lungs, abdominal cavity, lymph nodes and the chest wall, mesothelioma is considered to be in an advanced stage.

The oft used and the oldest system for determining the stages of mesothelioma is the Butchart System. The Butchart System is based on the extent of the primary tumor mass available in a patient. This system divides mesothelioma into four stages. The TNM system, a slightly advanced system over the Butchart System, determines staging through variables of tumor in mass and the spread, the lymph node involvement and metastasis. However, the latest system is known as the Brigham System, where staging is done as per the respectability and lymph node involvement. In spite of such modern techniques, a definitive diagnosis of mesothelioma still remains possible through fluid diagnosis and tissue biopsy.

Mesothelioma lung cancer is usually associated with asbestos exposure. In fact there are many other risk factors that cause mesothelioma cancer. One of them is the erionite. Erionite is a naturally occurring fibrous mineral that belongs to a group of minerals called zeolites. Zeolites are hydrated aluminosilicates of the alkaline and alkaline-earth metals.
Erionite was used in the past as a noble metal-impregnated catalyst in a hydrocarbon-cracking process. It was studied for use in fertilizers and to control odors in livestock production, because of its ability to selectively adsorb molecules from air or liquids. In many countries erionite blocks were used (and may be are still used) as building material or in stucco pastes and whitewash.
Erionite was mentioned for the first time as a mesothelioma lung cancer risk factor in 1975, when Turkish government presented a study that uncovered a high incidence of a rare malignant mesothelioma in lung tissues of people in certain small villages in the Cappadocia area in Turkey’s central mountainous region. In two small villages the mesothelioma lung cancer accounted for 43% of the deaths during 23 years period of study. Erionite fibers were found in biopsies of lungs of the mesothelioma cancer afflicted people. Comparing this to a 9.7% rate of death from this disease among asbestos insulation installers shows how anomalous this condition was.
Further studies showed erionite causes similar diseases in laboratory animals. When researchers at Mt. Sinai Hospital injected rats with the same dosage of erionite that they used for asbestos, the rats didn’t live long enough to get mesothelioma cancer. At a much-reduced dose, the rats did get cancer. Erionite is probably the most toxic known mineral - a milligram of fibers in the lungs is lethal.
Today erionite is considered so hazardous that the EPA requires any one who intends to manufacture, import or process any article containing erionite to notify the E.P.A. 90 days in advance. This gives the EPA a chance to review, limit or prohibit that activity. Read the rest of article here..

Mesothelioma is a form of cancer. It caused by previous exposure to asbestos. An exposure of as little as one or two months can result in mesothelioma 30 or 40 years later. Simian virus 40 (SV40) may act as a cofactor in the development of mesothelioma. Malignant mesothelioma is the most serious of all asbestos-related diseases. The two major types of malignant mesothelioma are pleural mesothelioma, which concerns the mesothelium membrane that surrounds the lungs, and peritoneal mesothelioma which concerns the mesothelium layer that covers the organs in the abdominal cavity. The people most at risk from being carriers of this cancer are those have worked with asbestos over the past thirty to fifty years. Because of this, the disease is most common in men between the ages of sixty and seventy as this is the group that commonly worked with asbestos during those years. Because of the lack of protection and regulations in those days, these workers were constantly exposed to the dust and fibres from the asbestos, which caused the cells of the mesothelium to become abnormal. Many building materials used in both public and domestic premises prior to the banning of asbestos may contain asbestos. Those performing renovation works or diy activities may expose themselves to asbestos dust.

Mesothelium helps protect the organs by producing a special lubricating fluid that allows organs to move around. Mesothelioma is an extremely malignant and incurable cancer that infects the membrane that surrounds most of the internal organs. Symptoms of mesothelioma may not appear until 20 to 50 years after exposure to asbestos. Shortness of breath, cough, and pain in the chest due to an accumulation of fluid in the pleural space are often symptoms of pleural mesothelioma. Affecting the mesothelial cells that make up the mesothelium – the outer lining that protects the body’s major organs such as the heart, stomach and lungs. Pleural mesothelioma represents 75% of mesothelioma cases - but it is far from the only type of this deadly cancer. Peritoneal mesothelioma affects the lining around the stomach and intestines, and is just as dangerous and deadly. Treatment of MM using conventional therapies has not proved successful and patients have a median survival time of 6 - 12 months after presentation. The clinical behaviour of the malignancy is affected by several factors including the continuous mesothelial surface of the pleural cavity

Mesothelioma Cancer Treatment and Prevention Tips

1. Health-care workers who specialize in part control are employing state-of-the art techniques to successfully fight pain.

2. During the initial stages of mesothelioma, pain can be relieved with over-the-counter analgesics, such as aspirin, Tylenol or ibuprofen (Advil, Motrin).

3. Drug therapy is the primary method for treating mesothelioma pain.

4. Non-Opoids are pain-relieving medicines such as acetaminophen (Tylenol) and NSAIDs, such as ibuprofin, which can be purchases over-the-counter and taken orally.

5. Opoids are the strongest medicines available to treat pain. Opoids, such as codeine, morphine, oxcodone, fentany, and hydromorphone, are very effective in relieving mesothelioma pain.

6. Adjuvant analgesics are medicines intended for purposes other than pain relief. A number of these are used to alleviate pain associated with mesothelioma, such as antidepressants, anticonvulsants, and steroids.

7. Emotional Support to Help Relieve Pain.As with all aspects of mesothelioma, emotional support from family or professional counseling can play a key role in pain management

8. For patients with localized disease, and who can tolerate a radical surgery, radiation is often given post-operatively as a consolidative treatment.

9. Chrysotile has been used more frequently, hence many mesotheliomas are caused by chrysotile.

10. Removal is taking place in schools and other public buildings throughout the U.S. The hope is that these measures will greatly reduce the occurrence of this cancer.

Malignant mesothelioma (cancer of the mesothelium) is a disease in which cells of the mesothelium become abnormal and divide without control or order. It is a rare form of cancer that most frequently arises from the cells lining the sacs of the chest (the pleura) or the abdomen (the peritoneum). Malignant mesothelioma is closely linked to exposure to asbestos - a natural fiber that was once used in manufacturing a wide variety of industrial and household products. Workers involved in asbestos mining, milling and manufacturing are at the greatest risk for developing malignant mesothelioma. Also at high risk are shipyard workers, workers in the heating and construction industries, and other tradespeople. Family members and others living with asbestos workers have an increased risk of developing malignant mesothelioma, and possibly other asbestos related diseases as well. Cases of malignant mesothelioma have even included people whose only exposure was breathing the air through ventilation systems.

Although reported incidence rates have increased in the past 20 years, malignant mesothelioma is still a relatively rare cancer. Between 1973 and 1984, there has been a threefold increase in the diagnosis of pleural mesothelioma in Caucasian males. From 1980 to the late 1990s, the death rate from malignant mesothelioma in the USA increased from 2,000 per year to 3,000, with men four times more likely to acquire it than women. The actual rates may be even higher however, since it is possible that many cases of malignant mesothelioma are misdiagnosed as adenocarcinoma of the lung, which is difficult to differentiate from mesothelioma.

The average age of diagnosis of malignant mesothelioma is 60. The average survival time varies from 4 to 18 months, and death is usually due to infection or respiratory failure from the progression of the mesothelioma.

One rare form of cancer is called Mesothelioma, a malignant tumor in the mesothelial tissues of the lungs and the abdomen, arising from the inhalation of asbestos. Its rarity is one of the reasons why a lot of people are not aware of this kind of fatal disease. In fact, many people die of Mesothelioma undiagnosed. Although there is now a growing awareness of the hazards of asbestos to health, still many have not heard of Mesothelioma and thus, have not understood its nature, cause, signs and treatment. Even some physicians find it hard to detect Mesothelioma because its symptoms are akin to other diseases like lung cancer and pneumonia. Furthermore, it takes decades for a patient who was exposed to asbestos to develop Mesothelioma — fifty years, at most.

Being unaware of Mesothelioma poses higher risks since it deters diagnosis and treatment. A person undergoing treatment must know the different stages of the cancer or the extent of the disease. Chances of recovering from Mesothelioma and the kind of treatment depend on the stage of the illness. There are basically two staging systems used for Pleural Mesothelioma (lungs): TNM system and Brighan system. These staging systems are also used in other kinds of cancers; however, the first is commonly used. There is no established method in determining the stage of the Peritoneal Mesothelioma cancer (abdominal) so the TNM system is used.

There are three variables in the TNM system: tumor, lymph nodes and metastasis. In the earliest stage of Mesothelioma, stage I, the malignant Mesothelioma cells start to grow and multiply only one layer of the pleura. The pleura is the membrane that encloses the lungs and lines the wall of the chest cavity. However, there are some instances wherein the pericardium (membrane that covers the heart) and diaphragm cover are already affected. In this case, the cancer patient is still in stage I Mesothelioma.

In the second stage, the two layers of the pleura are already affected by Mesothelioma. Take note, however, that in this stage, only one side of the body is affected. Normally, the pleura produces only small amount of lubricating fluid that allows easy expanding and contracting of the lungs. The excess fluid is absorbed by the blood and the lymph vessels so there’s a balance between the amount of fluid produced and removed. During the second stage Mesothelioma, fluid starts to build up between the membrane of the lungs and the membrane of the chest wall, resulting to pleural effusion. The increase in the volume of fluid produced causes shortness of breath and chest pain. Other Mesothelioma cancer patients experience dry and persistent cough. Diagnosis of the pleural effusion is achieved through a chest x-ray.

Stage III Mesothelioma means that the malignant cells have already spread to the chest wall, esophagus and the lymph nodes on one part of the chest. The patient may suffer severe pain near the parts affected. When not treated immediately or when the Mesothelioma patient doesn’t respond well to medication, the cancer may advance to the fourth stage. The fourth stage Mesothelioma is formidable since at this stage the Mesothelioma cells have penetrated into the bloodstream and other organs in the body like the liver, the bones and the brain. The lymph nodes on the other side of the chest may also be affected by Mesothelioma in stage IV.

Brighan staging system, on the other hand, determines whether the Mesothelioma can be surgically removed or not and whether the lymph nodes are affected or not. In stage I Mesothelioma, the lymph nodes are not yet affected and the patient can still recover through surgery. In stage II, surgery can still be executed but some lymph nodes have already been infiltrated by the cancer cells. In stage III, the heart and chest wall are already affected; thus, surgery is no longer advisable. The lymph nodes in this stage, however, may or may not be affected. In the final stage, stage IV Mesothelioma, cancer cells have already gone to the bloodstream and other parts of the body like the heart, brain, bone and liver. In most cases, a patient who has reached stage IV Mesothelioma only has four to twenty-four months to live.

Mesothelioma is a very rare form of lung cancer that arises in the mesothelium. The mesothelium is made up of parietal and visceral membranes, thin layers of tissue, which surround organs and body cavities, such as the lungs or abdomen. The visceral membrane immediately surrounds the organ, and the parietal membrane is a sac covering. The visceral and parietal membranes that make up the mesothelium. The mesothelium is referred to by different names, depending on what part of the body it is found in.

Dealing with mesothelioma

Dealing with mesothelioma is a very difficult process. It will require a lot of physical and emotional endurances. The best way to understand mesothelioma is to learn everything that you can learn about the disease. This should include the causes, symptoms, diagnosis, treatment and prognosis of mesothelioma- cancer of the lung lining.

Symptoms

Since mesothelioma-cancer of the lung lining takes a long time to develop inside a human body. It is often difficult to identify the symptoms. In the early stages there may not even be any symptoms at all. When they do appear the most common early symptoms are shortness of breath and chest pains.

Presentations and expectations

There are two major types of asbestos: chrysotile and amphibole. It is thought that exposure to the exposure to the amphibole form is more likely to cause mesothelioma-cancer of the lung lining. However, chrysotile has been used more frequently hence many mesothelioma are caused by chrysotile.

Removal is taking place in schools and other public buildings throughout the U.S. . The hope is that these measures will greatly reduce the occurrence of this cancer.

Long-term effects of the disease

A mesothelioma-cancer of the lung lining is a highly aggressive tumor that is generally deadly. Current treatment of malignant mesothelioma-cancer of the lung lining is designed to make the person with cancer comfortable.

Screening

There is no universally agreed protocol for screening people who have been exposed to asbestos. However some research indicates that the serum osteopontin level might be useful in screening asbestos- exposed people for mesothelioma. The level of soluble mesothelin- related protein is elevated in the serum of about 75% of patients at diagnosis and it has been suggested that it may be useful for screening.

Treatment

Once mesothelioma-cancer of lung lining has been diagnosed a treatment procedure can be recommended and begun. The correct treatment will depend on a number of factors. They include the location of the tumor, the stage of the disease and how far the cancer has spread in the patient. The recommendation will also depend on the age and overall health of the patient.

It is certainly not easy to deal with all of the medical, physical, emotional and financial issues that may be raised when dealing with a serious disease like mesothelioma-cancer of lung lining, but it always better to be prepared. We can just have a hope that in future as the medical science advances this incurable disease can also be cured and lives of many people can be saved.

Erionite is no longer mined or marketed for commercial purposes. Although other natural zeolites have many commercial uses (pet litter, soil conditioners, animal feed, waste-water treatment, gas absorbents, etc.) So potential occupational exposure to erionite occurs during the production and mining of other zeolites.

And there are questions:

Are there other mineralogical hazards like erionite and asbestos?

Should we expected mesothelioma lung cancer increases not only from asbestos exposure after another 20 - 30 years?

Almost all Mesothelioma cancer cases are due to asbestos exposure. Mesothelioma affects the protective lining of the body’s internal organs known as the Mesothelium. When you inhale air containing asbestos particles, the air directly affects the Mesothelium lining of the body. In most cases, the lungs and abdomen are affected the most.

Asbestos fibers are very fine and tiny and when they come into contact with the lungs of anyone who is exposed, it causes inflammation and the formation of scar tissue. This may then lead to Mesothelioma. The fibers become imbedded into the lungs and works through the membrane around it causing this type of cancer.

Asbestos is made of minerals with long thin fibrous crystals and it is flexible, strong and highly durable. Asbestos as also widely used in insulation because of its resistance to heat, electricity and chemical damage. Because it had so many good properties and was cheap to produce, it was used virtually everywhere and was in almost all buildings and houses. It was only until the 1960s that the link between Asbestos and Mesothelioma was discovered.

Abdominal Mesothelioma is caused when the fine Asbestos fibers find their way into the digestive system when swallowed. Again, this will affect the protective lining of the abdominal passage and may cause this type of cancer. Besides that, exposure to Asbestos may also cause person to suffer from chronic lung disease and respiratory problems.

People who are exposed to Asbestos on a daily basis like construction workers, factory workers or even those who live near asbestos factories are most likely to develop Mesothelioma. Since the link between this deadly cancer and asbestos was discovered, this material is no longer widely used. However, Mesothelioma may not surface for as long as 60 years after exposure. Therefore, anyone who came into contact with this material should be regularly checked for this cancer.

In some very rare cases, Mesothelioma does develop even if a person is not exposed to asbestos. The exact cause for this is still unknown and it may be due to genetics or family history. Since the link between asbestos and this cancer was discovered, home and buildings that used this material for insulation and building materials were removed. As there is a proven direct linkage between this material and Mesothelioma, we should all take extra precaution if were to come into contact with this deadly material. It is best to avoid being exposed to this harmful material at all cost.

Mesothelioma cancer is a disease that results from exposure to asbestos related substances. Asbestos usually consists of fibres that can enter the body through the mouth, or the skin, and, subsequently, enter the lungs, or blood stream.

Mesothelioma cancer has become more widely documented in the last 5-10 years, due to the fact that symptoms of asbestos cancer can take between 20 to 40 years to manifest. Mesothelioma cancer is hard to diagnose, as the symptoms do not tend to manifest themselves until the later stages of the disease. Symptoms of mesothelioma lung cancer include shortness of breath, chest pain, fever and other secondary illnesses such as pneumonia.

Asbestos cancer most often develops in men between the ages of 50 to 70 years who were exposed to high levels of asbestos in the workplace. Asbestos was mainly used in manufacturing industries such as automotive and ship building as well as in the construction industry. The use of asbestos was only recently banned in the 1990’s.

Mesthelioma lung cancer has been found to be the most common form of mesothelioma cancer and it develops in the lining of the lung (pleural). Mesothelioma cancer can also develop in the abdominal area (peritoneal) and around the heart (pericardial). There is a greater chance of malignancy in abdominal asbestos cancer. For a more detailed explanation of mesothelioma cancer, visit http://www.lung-canceradvice.com

Mesothelioma lung cancer can be detected through a CT scan which enables it to be sometimes diagnosed earlier than the other two types of mesothelioma cancer. The type of mesothelioma cancer treatment will depend on the stage at which the cancer was diagnosed, the age of the patient as well as personal preferences. The disease can be divided into four separate stages. The stage in the disease process that is reached will determine the method of mesothelioma cancer treatment. At the first stage when the tumour is confined to the lining of the lungs, surgeons may try to remove the entire tumour surgically. Once the tumour has invaded the surrounding body tissues in the later stages, it is not curable.

Conventionally, the more advanced stages of mesothelioma cancer are treated with either radiation therapy or chemotherapy. Radiation therapy utilizes high-energy x-rays to destroy cancerous cells and shrink tumours Chemotherapy, on the other hand, uses drugs to destroy cancer cells. The aim of these mesothelioma cancer treatments is to prolong the patient’s life as the disease cannot be cured in the more advanced stages.

In addition to these conventional mesothelioma cancer treatments, there are also various experimental treatments currently under investigation which offer new hope.

Immunotherapy: This form of biological therapy for mesothelioma cancer treatment uses the patient’s own immune system to attack the cancerous cells. Clinical studies have shown that the immune system is able to distinguish healthy cells from cancer cells, and can therefore be used to destroy those cancerous cells.

Gene Therapy: This form of mesothelioma cancer treatment is very much still in the developmental stages. The process involves injecting a specific gene straight into the tumour. This gene renders the cancer cells sensitive to the antiviral drug glanciclovir which under normal circumstances is not effective against these cells. The glanciclovir is then able to destroy all the cancer cells without harming the healthy tissue cells.

Drug Therapy: The drug Alimta is the only chemotherapy drug to be approved by the Food and Drug Administration (FDA)for the treatment of patients with malignant mesothelioma lung cancer . This new and exciting drug has been demonstrated in clinical trials to reduce symptoms and increase the life expectancy of patients.

Photodynamic Therapy: Photodynamic therapy involves the use of light to destroy cancer cells. The patient first is first administered a photosensitizing drug that only collects in cancerous cells. Fibre-optic cables are then inserted in the body in order to focus light of a certain frequency on the tumour. The light stimulates the photosensitizing drug to produce toxic oxygen molecules that destroy the cancerous cells.

These experimental mesothelioma cancer treatments, although still in the developmental stages, offer cancer victims the prospect of a better and longer life. With the likelihood of an increase in the number of people diagnosed with asbestos cancer, further research into other forms of mesothelioma cancer treatment is vital.
